One thing you may want to do after ya getter dialed in is check your compression to insure you didnt weeken the rings when it boiled over on you.Or even better do a leak down test like the guys suggested.

All right!
Buttoned up every thing and I must have over lashed the rocker arm because #1 had no compression. I backed it off a little and it fixed it.
Checked the fuse box and found a blown fuse for the ECM.
SES is flashing correctly now and I heard the MCS clicking briefly.
When i gound the SES the MCS starts clicking... is that normal?
It did start briefly after much cranking and a little carb spray.
However, it died quickly. I floored it and it started for about 10 seconds if I kept the accel. down.

Can't get it to stay running.
If I rev it to about 2500 RPM + it sounds the strongest I have heard it in a long time. Once it is below 1500 rpm she just dies.
I removed the air horn and checked the float per the instructions.
It is set correctly.
Where should i look first?

When you get it started again hit it with the carb clean and see if you can keep it running. Usually a mecanical fuel pump will contine to work when it goes bad but spews fuel into the engine and oil out the weep holes. If it contines to run with the stream of carb clean you may need to readjust the screw on the top of the carb or double check to make sure the float isnt bad bound or the needel and seat isnt plugged. you may alsos have the throttle blades closed too much for choke open operation.

Bingo
I decided if #1 did not get compression because I overlashed the rocker arms that it would be good to check the rest...Duh.
I backed each one off 1/4 turn.
Bam...like a bat out of hell she took off. Ran up to 3000 rpm and sounded incredible.
She leveled off @2500 rpm.
I shut her off and adjusted the fast idle cam and idle screw.
Right now she is sitting @ 1200 rpm and cannot get her any lower.
The idle screw is just about backed all the way out. The fast idle does not seem to adjust her any lower and the timing is about 4 degrees retarded.
How can I get her down to 800 or so?

Finally got her idling nicely and running like a champ!
Next problem, The oil pressure guage shows very low pressure (just above the red line). What is the best way to troubleshoot this?
